Caenomorpha (seen-owe-morph-a) medusula. Body medusoid with 1 to 3 posterior spines. Without somatic cilia except for a band which lies near the membranelles. The membranelles form a long spiral that encircles the body and ends in posteriorly situated cytostome. A contractile vacuole is located at the base of the spine. Symbiotic (methanogenic) bacteria occur in the cytoplasm. Move very quickly, with a jerky rotation. Between 1-4 macronuclei but always with only 1 micronucleus. Common in anoxic habitats. This specimen was collected in a bog near Konstanz, Germany. Slightly squashed specimen of Caenomorpha medusula. Focal plane on the rim of the bell-shaped anterior half of the body. Specimen measures 90 microns. Differential interference contrast. This picture was taken by Martin Kreutz using an Olympus microscope.
